Let G be a finite group, p a prime, P a Sylow p-subgroup of G and d a power of p such that 1<d<|P|. Let Gp denote the unique smallest normal subgroup of G for which the corresponding factor group is abelian of exponent dividing p1. Let 𝔉1, 𝔉2, 𝔉3 be classes of all p-groups, p-nilpotent groups and p-supersolvable groups, respectively, G𝔉 be the 𝔉-residual of G. Let X{(Gp)𝔉1,G𝔉2,G𝔉3}. A subgroup H of a finite group G is said to have Π-property in G, if for any G-chief factor L/K, |G/K:NG/K((HL)K/K)| is a π((HL)K/K)-number. A normal subgroup E of G is said to be p-hypercyclically embedded in G if every p-G-chief factor of E is cyclic, where p is a fixed prime. In this paper, we prove that E is p-hypercyclically embedded in G if and only if for some p-subgroups H of E, HX have Π-property in G.

关于有限群的子群的Π性质

G是一个有限群,p一个素数,西洛p-子群Gd一种力量p这样1<d<||. 让Gp*表示唯一的最小正规子群G对应的因子组是指数除法的阿贝尔p-1. 让𝔉1,𝔉2,𝔉3成为所有人的班级p-团体,p- 幂零群和p- 超可解组,分别,G𝔉成为𝔉-剩余的G. 让X{(Gp*)𝔉1,G𝔉2,G𝔉3}. 一个子群H有限群的G据说有Π- 财产G, 如果有的话G-主要因素大号/ķ,|G/ķñG/ķ((H大号)ķ/ķ)|是一个π((H大号)ķ/ķ)-数字。正态亚组G据说是p- 超循环嵌入G如果每个p-G- 主要因素是循环的,其中p是一个固定素数。在本文中,我们证明p- 超循环嵌入G当且仅当对于某些人p-亚群H,HXΠ- 财产G.
